Garmin Enduro 3: Six-Month Long-Term Review

By Hmmuller

After six months of daily wear, thousands of kilometers of cycling and hiking, here's the unfiltered truth about living with the Garmin Enduro 3.

After six months of forests, mountains, all kinds of weather, and even a 515 km endurance race, does the Garmin Enduro 3 actually hold up? The answer kind of surprised me — and it might just change the way you think about sport watches for extreme use. This is the unfiltered experience I’ve had after putting it at the center of all my adventures, training, and daily life.

Garmin has not sent me this watch to review. I bought it with my own money.

Why I switched from the Fenix 7

Before the Enduro 3, I had the Fenix 7 Sapphire Solar Edition — the 47 mm version. It had okay battery life for long-haul tracking, but nothing spectacular. At least in my opinion, and especially not compared with the Enduro 3. Compared to an Apple Watch, almost all Garmin watches are in a different league battery-wise. But even by Garmin standards, the Fenix 7 left me wanting more.

During a recent endurance race, my friend’s Fenix 7 Pro (47 mm) went from 100% charge down to just 15% by the end of a bright sunny day after tracking for about 17 hours. That’s the kind of battery anxiety I wanted to eliminate. I needed a watch that wasn’t just rugged but also 100% reliable for tracking my longest and most demanding races.

When the Garmin Enduro 3 hit the market, it was positioned as the endurance-specialized version of the Fenix 8 line. I wasn’t interested in the Fenix 8’s extra smart features like the microphone or speaker. I didn’t need an Inspector Gadget watch. I wanted a tool that behaved like a classical digital watch — which is why the memory-in-pixel screen, perfect in direct sunlight, was a huge draw for me.

Previous Enduros I didn’t like that much due to their green tint and accent. On this version it has been toned down considerably, and as a nice bonus, it was still $300 cheaper than the Fenix 8.

Build quality and comfort after six months

I am not particularly gentle with my gear. The Enduro 3 has been subject to falls, bumps, mud, and scratches. The scratch-resistant sapphire lens has proven as durable as expected — coming from a Fenix 7 with sapphire as well, this watch has no visible scratches at all. There are a few minor scratches on the titanium bezel, but you’ll have to look really closely to see them.

The nylon strap is fantastic. Super comfortable, and it has held up well even after being washed. The only significant wear is on the inner velcro from the friction of taking the watch on and off — which, if you put it on and off a bike mount as often as I do, is to be expected. I also have a TPU strap that I use for wet activities such as swimming.

For those worried the plastic casing might make the watch feel cheap: let me put that to rest. The plastic back actually makes it more comfortable, especially in winter when a full titanium back can feel uncomfortably cold against your skin. I’ve experienced this in freezing temperatures while cross-country skiing and backcountry skiing in -5°C.

Comfort might sound superficial, but for a device you wear 24/7, I think it’s critical. The default nylon strap is so comfortable that I wear it about 95% of the time. Now that I have a handlebar mount and an external heart rate monitor, I don’t even need the watch on my wrist for cycling — which is a nice bonus.

For a more urban look, I have the magnetic nylon strap from Alua, though the metal parts add some weight. You can also find plenty of third-party leather or metal bands if you want to dress it up, but for me nothing beats the everyday comfort of the nylon band. It’s anonymous enough to blend into many situations.

GPS, maps, and navigation

GPS accuracy has been consistent. There were some minor inconsistencies when using GPS-only mode in dense forest on a recent hiking trip, but I’ve had the same issue on the Fenix 7 — so that was expected. The pre-loaded topo maps have made my hikes more convenient and seamless.

For day hiking based on my testing, I don’t think you need anything other than the Enduro 3 if you’re following a preset course. For multi-day hikes, it’s a great companion for confirming you’re on track. Though I do prefer printed maps in conjunction with it, given that the screen size is a bit too small for detailed orientation. You can scroll around the terrain on the watch, but the level of detail and squinting can make it inconvenient.

We ended up using the map feature only when we wanted to know exactly where we were, then switched to printed maps. For safety on multi-day hikes out of cellular coverage, I also recommend getting a Garmin inReach Mini for satellite communication to stay in touch with loved ones and have a reliable tool for emergencies.

Pairing the Enduro 3 with a satellite communicator

For safety on multi-day hikes out of cellular coverage, I pair my Enduro 3 with a Garmin inReach Mini 2. Having a dedicated satellite communicator on your shoulder strap or in your pack adds a layer of safety that doesn’t depend on your watch’s battery. Here’s how the current options compare:

FeatureinReach Mini 2inReach Mini 3
Price$249.99$449.99
Screen0.9″ monochrome1.9″ color touchscreen
GNSSSingle-band GPSMulti-band GNSS
Battery1250 mAh (~12 days)1800 mAh (~13 days)
BasemapsNoYes
Built-in sirenNoYes
Weight~100 g~122 g

I recommend the inReach Mini 2 as the best value pairing with the Enduro 3. At nearly half the price of the Mini 3, it gives you everything you need for safety: SOS, two-way messaging, and location tracking via the Iridium satellite network. Since the Enduro 3 already has multi-band GNSS, detailed topo maps, and a large screen, you don’t need those features duplicated in your satellite communicator.

There’s also a practical consideration for colder climates: the Mini 2’s physical buttons work reliably with gloves and in freezing temperatures, while the Mini 3’s touchscreen can be difficult to operate in those conditions.

That said, if you want a standalone navigation device as a backup, the inReach Mini 3 with its color screen and basemaps is a genuine upgrade. There’s also a Mini 3 Plus at $499.99 that adds voice and photo messaging via satellite — useful if you want to send trail updates beyond simple text.

Training, cycling, and heart rate monitoring

The advanced training metrics from Garmin — training status, training readiness, recovery time — have been invaluable when preparing for my 515 km endurance cycling race and an upcoming mountain race. Earlier this spring, I let Garmin create a training plan for my endurance race and it gave me a program to follow. I also learned how to use acute load to see if my training was productive and how to maintain my fitness post-race. The endurance score has been very useful this fall to maintain my shape until the next season.

The activity I track most is cycling, with road biking and spinning being the most used. On the road, the Enduro 3 works as a bike computer in practice. I’ve covered this in my separate video, but in short: it’s fine for longer, more predictable stretches of road, but you’ll need something larger for urban navigation such as a dedicated Garmin GPS or even your phone. The fact that you can mount your watch on the handlebar is a huge plus — it’s faster and safer than glancing down at your wrist.

If you’re not using an external heart rate sensor, you might experience the built-in sensor lagging behind your actual heart rate variations, then suddenly snapping to your elevated heart rate — for example during a climb. An external chest strap is much more accurate and genuinely useful for knowing what heart rate zones you’re actually in. This has been especially important for my long zone 2 rides in preparation for endurance racing.

Choosing the right heart rate monitor

If you’re looking at an external chest strap to pair with your Enduro 3, here’s a quick overview of the current Garmin lineup:

FeatureHRM-200HRM-Pro PlusHRM-600
Price$79.99$129.99$169.99
BatteryCR2032, ~1 yearCR2032, ~1 yearRechargeable, ~2 months
Running dynamicsNoYesYes + step speed loss
Standalone recordingNoNoYes
Swimming HR storageNoYesYes
Water rating3 ATM5 ATM5 ATM
Detachable podYesNoYes

The HRM-200 is the best value option — ideal for cyclists and gym-goers who just need reliable heart rate and HRV data broadcast to their watch. It also has an encrypted Bluetooth mode, which is handy in crowded gym environments where signals can interfere.

The HRM-Pro Plus adds running dynamics (cadence, stride length, vertical oscillation, ground contact time) and swimming heart rate storage. It’s being phased out by the HRM-600, but remains a solid mid-tier option if you find it on sale.

The HRM-600 is Garmin’s new flagship chest strap. It adds standalone activity recording — meaning it can track workouts to Garmin Connect without a watch — a rechargeable battery, and a new “step speed loss” metric for runners. If you’re a triathlete or serious runner, this is the one to get.

The flashlight and everyday features

The LED flashlight is a feature I never knew I needed and now can’t live without. It is surprisingly bright, adjustable, and incredibly convenient. Whether it’s finding something in the dark on a hiking trip or just taking a quick look around without pulling out a phone, I use it almost daily.

On my last hiking trip, I used it in a cabin without electricity to check on the water we were boiling, and to take a last look around the room before leaving. The red LED for situations where you don’t want to tamper with your night vision is great too.

For strength training, the Enduro 3’s interface is now more useful than ever. It’s easy to correct the number of repetitions per set and the amount of weight. When you have a training plan set up in Garmin Connect, the watch gives you relevant strength exercises with an animation on screen — which is a lot better for knowing exactly how an exercise is performed.

Garmin Pay is a feature I use almost daily. I now pay with my physical card maybe once or twice a year. I also use the countdown timer constantly for cooking, and I’m happy the interface has gotten a bit of an overhaul.

Battery life in the real world

Now to my favorite feature — and probably the most boring to talk about: battery life. While Garmin’s claims of 90 days in smartwatch mode are likely based on lab-like settings, real-world use has been impressive.

As a very active user tracking workouts almost daily, using maps, the flashlight on a daily basis, and sometimes music playback from the watch, I get about two weeks of battery life. On a multi-day hike with a lot of sunlight and moderate map use in satellite mode set to GPS only, I saw about 10% battery drain over a tracking length of 8 hours.

You can of course charge it with a power bank, but the convenience of ultra-long battery life leaves you with more power to spare for your other devices — your phone or satellite communicator. While you rarely need to charge it, it does take a while to get to 100%. But that’s a minor nitpick given how long it lasts and the fact that charging happens only about every second week.

What I don’t love

No watch is perfect, and after six months I’ve found a few challenges:

  • It’s a large watch. At 51 mm, it’s not for everyone. Thanks to the lightweight nylon strap it doesn’t feel overly heavy at just 63 grams, but it can occasionally snag on jacket sleeves.
  • The price is high. It’s a significant investment, but you’re essentially buying multiple devices in one: a health tracker, training tool, hiking GPS, bike computer, flashlight, and music player.
  • Slow charging. While you rarely need to charge it, getting to 100% takes a while. A minor nitpick given the overall battery performance.

Who should buy the Enduro 3?

After six months, the Garmin Enduro 3 has truly lived up to my expectations. It’s more than a watch. It has transformed my race preparation — I no longer worry about running out of battery, I feel safer on unknown trails following a set course, and I have better insight into my training status and overall endurance. I now know what it takes to train for the next season thanks to the acute load metric.

So is the Garmin Enduro 3 for you? A resounding yes if you are:

  • An ultrarunner or endurance cyclist
  • A frequent hiker or multi-sport athlete
  • Someone who needs or wants maximum battery life in a sport watch
  • Someone who thinks the Fenix 8 is too expensive or has features they don’t need

If you find the price of the Enduro 3 too high, the Garmin Instinct 3 offers a lot of the same features with a few exceptions. The major difference is the screen: the Enduro 3 has full topo maps, while the Instinct 3 can only follow a breadcrumb trail. The design of the Instinct 3 isn’t for everyone either.

If you want similar features in a sleeker package and different sizes, the older Fenix 7 Pro series is also worth a look. I think it’s the biggest competitor to the Enduro 3 — the differences between them are not huge, it’s cheaper, and it comes in different sizes. You’re getting less battery life and don’t get the latest software features, but it remains a very good option.
